SEPARABLE SCREEN -HINGE.

SPECIFICATION forming part of Letters Patent No. 699,698, dated May 13,1902.

Application filed August '7, 1901. Serial No. 71,147. (No model.)

To all whom it may concern:

Be it known that 1, MICHAEL W. MURRAY, a citizen of the United States,residing at Milton, in the county of Norfolk and State of Massachusetts,have invented an Improvement in Separable Screen-Hinges, of which thefollowing description, in connection with the accompanying drawings, isa specification, like letters on the drawings representing like parts.

My invention is an improvement in hinges for screen-doors and analogoussituations, its object being to provide a hinge having a part to befixed permanently on the door casing or post and a main portion or hingepart proper separable from said permanently-fixed part to be secured tothe door in order that the latter may be readily removed for storage inthe winter or for any other purpose required.

The details of construction of my invention will appear more fully inthe course of the following description, reference being had to theaccompanying drawings, in which I have shown one embodiment ofmyinvention.

In the drawings, Figure I is a fragmentary View in front elevation,showing a portion of a screen and the adjacent door-jamb with myinvention shown in plan applied thereto. Fig. 2 is an edge elevation ofthe entire hinge. Fig. 3 is a top plan view of the portion of the hingewhich is to be permanently affixed to the door casing or jamb. Fig. 4 isan end elevation thereof.

According to the present embodiment of myinvention, the hinge comprisesthree plate portions A B O, the latter two being provided at their endswith upwardly-projecting ears I) 0, connected by a pintle d, aroundwhich is Wrapped a coiled spring 3, said spring being preferably coiledreversely from its extended middle portion 3, which engages the part 0,and the free ends 8 of said spring projecting laterally for a purposepresently to be described.

The plate B contains adjacent its opposite edges two openings Z), andthe plate A has two lugs a, provided with overhanging lips orprojections a, so that when the plate Bis placed over the plate A thelugs a will project through the holes I) and the lips a will be removedfrom the surface of the plate B sufficiently to permit the free ends .9of the springs s to engage beneath them and hold the plates A B snuglyin interlocking relatively immovable relation.

It will be understood that I do not restrict my invention to the precisedetails of construction shown, as the interlocking and relativelycooperating parts and construction described may be'secured in variousmodified forms within the spirit and scope of my claims, as set forthhereinafter.

In use the plate 0 is secured by screws 0 or other usual manner to theadjacent edge of a screen-door E, and the plate A is similarly securedto the door post, casing, or jamb P. Then the screen-door, with theattached parts B C of the hinge, is put in place, so that theopenings 1) inclose the lugs a of the plate A, and the free ends 5 ofthe spring are snapped in place beneath the overhanging lips a, therebylocking the removable part and stationary part of the hinge rigidly inplace.

The weight of the door comes on the sides of the lugs A, which may be asheavy and strong for this purpose as may be desired, and the spring ends3 prevent any possibility of the two parts A B getting apart.

When winter comes and it is desired to remove the screen-doors from thehouse, all that is necessary is to grasp the two ends 8 of the springsbetween the thumb and forefinger and upon pressing them together pullthe door and part B of the hinge away from the part A, thereby instantlyremoving the door.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. A separable hinge comprising a portion adapted to be permanentlysecured to a sta tionary part, and a portion adapted to be secured to amovable part, the latter portion comprising a plate to be secured tosaid movable part, and a plate pivoted thereon, said pivoted plate andsaid permanent portion having interlocking lugs and apertures to receivesaid lugs, said lugs filling said apertures, said lugs havingoverhanging portions a projecting toward each other, and means forengaging beneath said lu'gs against the plates having the apertures forholding the separable parts of the hinge together.

2. A separable hinge comprising two plates to rest beneath saidoverhanging portions for pivoted together and a spring for yieldinglylocking the two parts together. holding said plates apart, one of saidplates In testimony whereof I have signed my having means for securingit to a door, and name to this specification in the presence of 5 theother of said plates having opposite aptwosnbscribing witnesses.
